What are the four features of a clinical thermometer?
Answer: Sensitivity, Linearity, Responsiveness of clinical thermometers are the same as that of laboratory thermometers. Range: The scale ranges between 35°C to 42°C. This range is centered around the normal body temperature of 36.9°C.
What are two features of a thermometer?
A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale …
What are the characteristic features of a mercury clinical thermometer Class 7?
WHAT ARE THE CHARACTERISTIC FEATURES OF A MERCURY CLINICAL THERMOMETER?
- A clinical thermometer is a thermometer use to measure body temperature.
- Often the liquid inside it is mercury.
- It is very accurate because it has narrow place where the liquid rises very fast.
What are the three uses of clinical thermometer?
Uses of a Clinical Thermometer
- Human Body Temperature.
- Animal Body Temperature.
- Predicting Female Fertility.
- Note.
Which is not a common feature in laboratory and clinical thermometer?
The clinical thermometer is used to measure body temperature, however, laboratory thermometer is not used for the purpose of measuring body temperature. The temperature range of clinical thermometers is 35°C to 42°C and that of laboratory thermometers is -10°C to 110°C.
What features of the laboratory thermometer make it responsive?
Responsiveness:
- As the liquid is contained in a thin-walled, small glass bulb, it will be more responsive (faster response) to heat.
- Mercury reacts quickly to the temperature changes whereas alcohol reacts slowly.
- It takes several tens of seconds to record one reading.
What do you mean by a clinical thermometer?
: a thermometer for measuring body temperature that has a constriction in the tube above the bulb preventing movement of the column of liquid downward once it has reached its maximum temperature so that it continues to indicate the maximum temperature until the liquid is shaken back down into the bulb.
What are the features of mercury thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
What are the characteristic features of mercury in thermometer?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
What is clinical thermometer?
What are the 5 difference between clinical thermometer and laboratory thermometer?
The clinical thermometer is used to measure body temperature, whereas laboratory thermometer is used for the purpose of measuring temperatures of hot substances in experiments in the laboratory. The temperature range of clinical thermometers is 35°C to 42°C and that of laboratory thermometers is -10°C to 110°C.
What is difference between laboratory thermometer and clinical thermometer?
Clinical thermometer is used to measure the human body temperature. A laboratory thermometer is not used for this purpose of measuring body temperature; it is generally used for the measurement of objects which generally have a temperature range outside that of a normal human body.
What makes a clinical thermometer sensitive?
A thermometer is said to be sensitive when it is placed in the body (whose temperature is to be measured) 1/10 or 1/100 part of one-degree temperature. For a small change of temperature more change in the height of the liquid column.
What two features affect the sensitivity of the thermometer?
The Sensitivity of Liquid Thermometers
- Using a thermometer with a larger glass bulb, as a larger bulb contains more liquid and therefore, allows for a larger change in the level of the liquid in the tube.
- Using a narrow tube, as a small change in volume results in the liquid moving a larger distance along the tube.
Which metal is used in clinical thermometer?
Mercury
Mercury is used in thermometer.
What is clinical thermometer short answer?
What are the three differences between clinical and laboratory thermometer?
Solution
| Clinical thermometer | Laboratory thermometer |
|---|---|
| 1. The range of temperature is low | The range of temperature is high |
| 2. It has a kink(constriction) in it | It has no kink in it |
| 3. It is used to measure human body temperature | It is used to measure the temperature of chemical reactions |
